This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Funds are provided to deploy a single, strategically placed mooring in the core of the western Arctic boundary current east of Barrow Canyon, which will collect measurements permitting estimation of both the alongstream and cross-stream fluxes of important physical, chemical, and biological quantities. These measurements will enhance our understanding of the western Arctic ocean-atmosphere-ice system, including crucial aspects of the ecosystem that are unattainable throughout most of the year due to ice cover. Analysis of a previously deployed high-resolution mooring array at the site has enabled the PI to determine the optimal placement and design of the mooring, and has given him insights into the vast amount of information that can be obtained from such a time-series. Using new generation moored profilers, the mooring will provide full-water column traces (from near the seafloor to the underside of the ice) of temperature, salinity, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, nitrate, backscatter (a proxy for zooplankton) and velocity. In addition, the mooring will provide time-series of ice thickness and ice velocity, bottom pressure, and marine mammal calls.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。资金用于在巴罗峡谷以东的北极西部边界流的核心部署一个单一的、战略性的系泊点，该系泊点将收集测量数据，以便估计重要的物理、化学和生物数量的沿流和跨流通量。这些测量将增强我们对北极西部海洋-大气-冰系统的了解，包括由于冰层覆盖而在一年中的大部分时间无法获得的生态系统的关键方面。通过对先前部署在现场的高分辨率系泊阵列的分析，PI能够确定系泊的最佳位置和设计，并使他能够从这样一个时间序列中获得大量信息。使用新一代系泊剖面仪，系泊将提供水温、盐度、溶解氧、pH值、浊度、叶绿素荧光、硝酸盐、反向散射（浮游动物的代表）和速度的全水柱轨迹（从海底附近到冰的底部）。此外，系泊将提供冰层厚度、冰速、底部压力和海洋哺乳动物叫声的时间序列。
